Automatic Transaxle; Mechanical System Test - Mazda 2002 6 Workshop Manual

MECHANICAL SYSTEM TEST

Mechanical System Test Preparation
1. Engage the parking brake and use wheel chocks at the front and rear of the wheels.
2. Inspect the engine coolant. (See
3. Inspect the engine oil. (See
4. Inspect the ATF levels. (See
5. Inspect the idle speed and ignition timing in P position. (See
IGNITION TIMING INSPECTION.)
6. Bring up the engine and transaxle to normal operating temperature.
Line Pressure Test
1. Perform mechanical system test preparation. (See
Warning
• Removing the square-head plug when the ATF is hot can be dangerous. Hot ATF can come out of
the opening and badly burn you. Before removing the square-head plug, allow the ATF to cool.
2. Connect the SSTs (49 H019 002 and, 49 0378
400C) to the line pressure inspection port, then
replace the gauge of the SST (49 0378 400C)
with the SST (49 B019 901B).
3. Start the engine, then warm up the automatic
transaxle.
4. Shift the selector lever to D range.
5. Read the line pressure at idle engine speed for
the D range.
6. Read the line pressure at idle engine speed for
the D (HOLD), S, S (HOLD), L, L (HOLD) ranges
and R positions in the same manner as in Steps
4-5.
7. Stop the engine, then replace the SST (49 B019
901B) with the gauge of the SST (49 0378 400C).
8. Start the engine.
9. Firmly depress the brake pedal with the left foot.
10. Shift the selector lever to D range position.
Caution
• If the accelerator pedal is pressed for longer than 5 seconds while the brake pedal is pressed, the
transaxle could be damaged. Therefore, perform Steps 11 and 12 within 5 seconds each.
11. Gradually depress the accelerator pedal with the right foot.
12. When the engine speed no longer increases, quickly read the line pressure and release the accelerator pedal.
13. Shift the selector lever to N position and let the engine idle for 1 minute or more to cool the ATF.
14. Read the line pressure at the engine stall speed for the D, D (HOLD), S, S (HOLD), L, L(HOLD) ranges and R
position in the same manner as in Steps 9-13.

Warning
• Removing the square-head plug when the ATF is hot can be dangerous. Hot ATF can come out of
